Application filed March 27, 1925.

To all whom it may concern:

Be it known that I, ALVIN HART, a citizen of the United ing at Ebensburg, andv State of Pennsylvania, have invent a certain new and useful Automobile Horn, of which the following is a specification.

This invention, generally stated, relates to automobile horns, and has more especial relation to automobile horns actuated by the the internal combustion or from a source of compressed gas or air calculated to be operated through the instrumentality of a hand pressed bulb and rubber 1 tube connection.

The leading object of the present invention is to provide a simple, efiicient, and comparatively inexpensive horn of the character stated in which an oscillatory is employed which may be maintained in a constant state of oscillation during supply of the source of actuating force.

A further object of the present invention resides in the provision of general details of construction and arrangement and combination of parts for attaining the results sought by the leading object. Other and further objects not at this time more specifically referred to will be hereinafter described.

The invention consists of the novel construction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with theaccompanying drawings forming part hereof, and in which.

Fig. 1', is a view in side elevation, partly 49 sectioned, illustrating more or less diagrammatieally an automobile horn as connect/e to the exhaust pipe of an internal combustion engine.

' ment with I against Serial No. 18,660.

' Fig. 6, is. a fragmentary viewv in section illustrating a further modified form of the invention; and

Fig. 7, is a v1 ew in section taken upon the For the purposehf illustrating my invention I have shown in the accompanying drawings several forms thereof which are at present preferred by me, have been found in practice factory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the reeise arrangement and organization of the mstrument-alities'as herein shown and scribed.

Referring to the drawings in detail the reference numeral 1 designates an automobile horn which is horizontally arranged and the neck 2 of which terminates in a substantially spherical shaped portion com prised of detachably arranged sections 3 and 4. Referring now more particularly to Figs. 1 to 3 inclusive, clamped as at 5 between the sections 3 and 4 a fixed plate 6. Fixed to plate 6 in any appropriate manner is thefiangc 7 of a horizontally arranged pipe 8 which pipe is projected through the section 4 and is connected by a union 9 with a pipe 10. The fixed plate 6 is apertnred as at 31 in alignthe said pipe 8. The pipe 10 to a valve 11 interposed in the pipe section 12 leading from the exhaust of an internal combustion engine (not shown). Secured with rcspect to plate 6 so as to be afl'ordedan oscillatory movement with respect thereto is a disc 13. In practice the .disc 13 is secured to plate (5 by means of bolts 1-l provided with sleeves 15 titted over said bolts so that the aperture portion 16 ofthe disc 13 may have longitudinal movement over said sleeves. The disc 13 may be made of/fnetal or any other suitable material calculated to give an audible sound when theexhaust from the internal combustion engine is permitted to pass through pipes 10 and 8, for impinging said 11%. obviousl instea of the pipe 10 connected with the into give satisis coupled having since the same there is shown as being terna-l combustion of an engine said pipe 10 may be connected to a source of compressed gas or air. The valve 11 may be operated from .the drivers seat by means of a pull chain 17. If compressed gas or air is the source of supply desired, obviousl a bulb for hand compression and a rub tube may be substituted for the valved connection. At such times as the operator of the automobile, motor boat, or the like, desires to operate the above described horn,

' valve llis open to permit the engine exhaust to pass through pipes10 and8 for imping= .ing against disc 13. Since the pressure 1. passing between the plate 6, and disc 13 moves at such velocity that-the pressure is less than the atmospheric pressure upon the horn side of the disc 13 the oscillatory plate is moved toward the fixed plate 6 only to ".be moved away again by the impinging exhaust. Thus as the oscillatory plate 13 is free t6 move in opposite directions and since pressure may be exerted upon opposite sides thereof it is apparent that the oscillatory 95 disc may maintained in a constant state of oscillation at desired intervals. Referring now more pecially to Figs. 4 and 5 the fixed plate 6 is the same as that shown in Figs. 1 to 3 inclusive but an additional 30 fixed plate 18- is provided interposed be: tween which fixed plates 6 and 18 is the oscillatory plate 19 which is central] aper tured as at 20. The plate 18 is xed to plate 6 by means of bolts 21, sleeves 22 being provided to maintain plate 18 in spaced re lation from plate 6 and the aperture'd portions of the disc 19 ermit disc 19 to move toward and away our plates 6* and 18. Otherwise the construction is the same as above recited and the operation is thesame.

Referring to Figs. 6 and 7, a pair of fixed discs designated 23 and 24 respectively are provided, said discs being secured to the sections 3 and 4 by means of braces 25 and 26. Between these fixed plates 23 and 24 is arranged an oscillatory plate 27 centrally apertured as at 28, bolts 29 and sleeves 30 ing provided as in the foregoing figures to permit oscillatory movement of disc 27 with respect to plates 23 and 24.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiments thereof which have been found in practice to give satisfactory and reliable results, it is to be understood that'the same are susceptible of modification in various particulars without departing from the spirit or horizontally into said compartment, said plpe being rigidly connected with the fixed plate for conve ing a medium under pressure for displacing said oscillatory disc.

2. In a device of the character stated the combination of a horn, a closed compartment in communication With said horn, a fixed plate arranged within said compartfment, an oscillatory disc arranged for movement toward and away from said fixed plate and normally displaceab-le under the influence of atmospheric pressure, bolts provided with sleeves carried by the fixed plate and upon which sleeves said oscillatory plate is movable, and a pipe extending into the said compartment and connected with the fixed plate for conveying a medium I under pressure for displacing said oscillatory disc.

3. In a device of the character stated the combination of a horn, a closed compartment in communication with said horn, said compartment being comprised of a pair of substantially hemispherical shells clamped together, a fixed plate arranged within said compartment, an oscillatory disc arranged for movement toward and away from said fixed plate and normally displaceable under the influence of atmospheric pressure, and a pipe extending into said compartment and connected with the fixed plate for conveying a medium under pressure for displacing said oscillatory disc.

1. In a device of the character stated the combination of a horn, ment in connection with said horn, a fixed plate within said compartment, an oscillatory disc arranged for movement toward and away from said plate, an internahcombustion engine exhaust, a pipe extending from said'exhaust pipe through said compartmeiijtnnd connected to the fixed plate which plate is aperturjia'd in connection with said pipe, and manually operable means for regulatmg the supply of pressure from .said ex aust tosaid compartment.

In testimony whereof, I have hereunto signed my name.
